GY-273 QMC5883L 3-Axis Compass Magnetometer Sensor Module IIC/I2C

Product details of GY-273 QMC5883L 3-Axis Compass Magnetometer Sensor Module IIC/I2C
The HMC5883L is a triple-axis magnetometer compass, which uses I2C for communication. Compass heading accuracy of 1° to 2°, provided by internal 12-bit ADC (Analog-to-Digital Converter). Includes on-board voltage regulator, allowing you to power the module with voltages between 3.3V and 6V. The module includes on-board pull-up resistors on the I2C lines.
